GSK2190915 is a high affinity 5-lipoxygenase-activating protein (FLAP) inhibitor that attenuates the production of leukotrienes through the blockage of the first step in the leukotriene pathway, 5-lipoxygenase (5-LO) activation. Leukotrienes are potent inflammatory molecules produced mainly by mast cells, eosinophils, monocytes/macrophage and neutrophils in response to allergic or inflammatory stimuli. GSK2190915 inhibits the production of leukotriene B4 (LTB4) and cysteinyl leukotrienes (cysLTs).
